Hello,
We are interested in capturing infrared images in addition to RGB and depth. We know that the Astra 2 has an infrared sensor, but when we activate it, a dot pattern appears, which I understand is used to calculate depth. Is it possible to capture these infrared images without this dot pattern? I assume the pattern would need to be deactivated.
Hello,
Yes, you should be able to disable the pattern, either through the OrbbecViewer (Device Control > Laser Control > Laser Enable > Off), or with the Orbbec SDK (e.g., python):
device.set_bool_property(OBPropertyID.OB_PROP_LASER_BOOL, False)
(see pyorbbecsdk/docs/README_EN.md at main · orbbec/pyorbbecsdk · GitHub)
Note that this greatly decreases the images brightness, so you might be left with a black image, depending on your setup.
